infratemporal region

Alveolar branches of the maxillary nerve go from the pterygopalatine fossa to the infratemporal region via this fissure.

Stage IV is a large tumor involving intracranial or infratemporal regions, an extensive neck disease, and/or any distant metastasis.

The stylomandibular ligament separates the infratemporal region (anterior) from the parotid region (posterior), and runs from the styloid process to the angle of the mandible.
